PFAS IN BEDROCK: THE UNDERLYING ISSUE
Now that PFOA and PFOS have been designated Hazardous Substances under CERCLA, these “forever chemicals” are frequently included in Environmental Site Assessments (ESAs) and remediation projects. However, underlying bedrock can make analyzing chemical contamination challenging. In fractured rock with primary porosity of as little as 1%, the vast majority of the contaminant mass may be present in the rock matrix rather than the fractures.
COREDFN FOR BEDROCK ANALYSIS
The CORE Discrete Fracture Network Approach (COREDFN) was developed by the University of Guelph / Morwick G360 Groundwater Research Institute to assess contaminant mass distribution in both the secondary porosity (fracture) and the primary porosity (matrix). This high-resolution approach assesses contaminant mass distribution and identifies which fractures are active transport pathways (not just hydraulically active ones). Through our exclusive licensing agreement, Pace® COREDFN testing services provide analytical results that allow users to assess contaminant levels and distribution, transport pathways, and the occurrence (or non-occurrence) of matrix diffusion within the rock environment.
CASE STUDY: ANALYZING PFAS IN BEDROCK USING COREDFN
Pace® has frequently used COREDFN to analyze bedrock for volatile organic compounds (VOCs), such as trichloroethylene (TCE), for our clients. However, when we were called on to analyze PFAS contamination during a PFAS Remedial Investigation at a Superfund site with known PFAS contamination extending into bedrock, COREDFN needed to be adapted to the unique characteristics of this emerging contaminant family.
